Passat 3C Project: Next Steps & Details

Hello!

After my Passat (3B) has had its service, I will be focusing on my girlfriend's car.


Engine code: CBAB (140 hp common rail).
Year of manufacture: 2008.
Mileage: 179,000 km

A heat pump system combined with a wood-burning stove is definitely being considered.
Since I'm not very familiar with the 3C yet, my question is:

What other changes would you make, or what needs to be changed?

Furthermore: Do I need any special tools?

Sure, here's the translation:

'Thank you in advance.'

Best regards,
Manuel

Sure, here is the translation of the text from German to English:

"Hi,"

Yes, special tools are recommended (e.g., a crankshaft locking tool). There's likely also something to lock the high-pressure pump in place. Also, you'll need a wrench to turn (adjust) the tensioner pulley.

Best regards, Rainer.

In addition, I would like to add that a few markings on the pulleys made with a marker are not necessarily a defect, especially if you don't have a routine for such things.

We've already seen enough artists around here who ended up in the wrong place with unfortunate consequences.

Okay, as Rainer already mentioned, you'll need a crankshaft locking tool, two camshaft alignment pins, and the fuel pump impeller. Drill bits might also be useful (possibly 8mm?).
"For the tensioning roller, you'll need a 6mm Allen key. Be very careful with the valve timing and make sure the dowel pin can slide in and out of its hole easily."

It's also important to properly bleed the cooling system. We do this using a vacuum pump.
